I think the blood moves in veins similarly to arteries but in the opposite direction. I mean as the heart pushes the blood into arteries, in an opposite way when heart is contracted the blood is pulled to it as a reaction for the action of pushing.

What is the force exerted by blood as it moves through the blood vessels?
This is called blood pressure. Blood pressure is measured in two parts. The first number is the systolic blood pressure and this shows the pressure exerted on artery walls when the ventricles contract and pump blood into the arteries and around the body. The second number is the diastolic blood pressure and this shows the pressure in the arteries when the heart is at rest and refilling ready for the next contraction.Blood pressureThis is known as blood pressure. The pressure high is during systole (when the heart pumps blood to the body) and a pressure low during diastole (when the heart is receiving blood back from the body)This is sometimes referred to as arterial pressure and different measurements are made regarding the arterial pressure such as the mean arterial pressure (MAP).
What is heart pressure?
No such thingBlood pressure (BP) is the pressure (force per unit area) exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs. The pressure of the circulating blood decreases as it moves away from the heart through arteries and capillaries, and toward the heart through veins.
In which type of blood vessel is blood at its highest blood pressure?
Aorta has highest pressure. Pressure gradually decreases as blood moves towards heart.
As the blood moves away away from the heart does the blood pressure increase or decrese?
The pressure decreases as it moves away from the heart.
As blood moves through heart blood pressure increases or decreases?
What occurs as blood moves away from the heart? pulse decreases blood pressure increases pulse increases blood pressure decreases
Does pressure drop when blood moves from arteries to veins?
Yes. Blood always flows from a higher pressure to a lower pressure, so as the blood moves from the arteries through the capillaries and into the veins pressure drops considerably.
What moves blood through the blood vessels?
Your heart. Your heart pumps and that moves the blood.
What happens to blood pressure as blood moves from arteries to veins?
Blood pressure decreases as blood moves from arteries to veins. For this reason, veins have valves to encourage the one-way flow of blood back to the heart.
GAses like oxygen and carbon dioxide move across cell membrane using what?
It moves by diffusion and partial pressure. You breathe in several gasses and each has its own individual pressure. The pressure of O2 in the air we breathe is greater than the pressure in the blood vessels in our lungs. The blood in your lungs is low because it has been depleted by body tissues. So high pressure in air and low pressure in blood means air moves into the blood stream. Carbon dioxide pressure in the blood is high because tissues have been creating it through aerobic respiration and its higher than the pressure of carbon dioxide in the air so CO2 passes from the blood into the lungs.

Why does blood come out slowly when drawing blood?
Blood draws normally occur through veins, though which blood moves slowly. There is low pressure and little muscular activity in the veins, resulting in lower pressure.
Why does blood pressure in aorta decrease further form heart?
As the blood moves through the aorta, the friction of the walls of the aorta decreases velocity. This velocity decrease results in a decrease in pressure.
What does the bottom reading on the blood pressure mean?
Blood pressure is the pressure of the blood pushing against the walls of your blood vessels. The top number (systolic) is the pressure during a heartbeat. The bottom number (diastolic) is the presurre between heatbeats or at rest --R Jackson LPN
